Follow Roswell, New Mexico

Isobel: The memory wasn't mine. I'm telling you. It was like someone else was inside of my body. Like they were using it. I can influence someone, but this fourth alien was much stronger. They were controlling me. It's like I wasn't even present. Liz: So, we're back to square one. Anyone could have killed my sister. Michael: Someone's guilty. Rosa was just the beginning. Max: Except for Rosa, all of the victims were targeted after a Chenai at the Last Pony, Maria's meal for the disenfranchised.

Liz: I'm gonna head to the hospital. The killer took my serum when they wrecked my lab. We need to make more. Only one dose left. Isobel: How does the killer know about the serum?Michael: The killer seems to know about everything. They could have possessed anyone at any time. They could have overheard us. Max: They've gotten away with 14 murders. They need to believe they're still in the clear.
